[Blind Archer]

As convenient as it is to snag then let swim , a deeply hooked treble will injure and kill just as you've pointed out. An easy and effective alternative is to retrieve the bunker and switch it to a pole with a circle or j hook. Chosing where to hook the bunker also enables you to control where it swims. I have a small egg sinker pinned up the line to bring it to the bottom of the pod.
